this is my first project on .net
actually i want know is there any way by which i can run my project by double clicking on an icon so that no onecan see my inside project code

If you go to the folder of your project in the "visual studio"-folder, in the folder bin -> debug, you'll find an executable file of your program.

You can always make setup of your program so that no one can see the code :)
Hint: Use Setup and Deployment Wizard.

Go to Project Menu in Visual Studio.You can see the publish menu at the end.Click on that .You will get a wizard.Hust specify the folder where you want to save.It may take ferw seconds based on your file size and a setup package will be created.It can be distributed to any pc and can be executed.Thank you
